i Toall it may concern:

Y Be it known thatI, Gnovnn C. NnwLUN, afcitizen of the United States, residing at Colville, in the county of Stevens, State of Washington, have invented a new and usef ulV Waste-Gas-Collecting Device; and I do hereby declare the following to be afull, clear, and exact description of theinvention, suchas will enable others skilled in tlie' art to which it appertains to make and u'setlie same. 'i A'Ihis invention relates to an improved waste chargev or gas collecting device for internal combustion engines of automobiles. In internal combustion origines it has been found that portions of the charge leak past thejpiston, Aparticularly on the compression strbkebf the piston 'and into the crank case, therefore, one of the objects of the invention is to 4provide an improved device for collecting and conveying the waste portions pfthecharge back to the arbureter, in order to ini-X ,with the subsequent charges.

u ljfA further object of the invention is the ,A "provison of means for permitting of an i auxiliary supply of air to be drawn into and 'nii'xed withthe waste portions of the charge onf its course back to the carbureter.

Ifurther object of the invention is to provide a simple, etiicient and practical deand which may be easily applied to automobile. internal combustion engines without making any alterations in the structure of the engine. j

In practicalields the details of constructionlmay necessitate alteration falling with in theasopel of 'what is claimed.

Theeinventon comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

'In the' drawings Figure 1 is a view of an internal combustion engine of an automobile,l the hood of which automobile is in section in order to show vthe waste charge collecting device applied.

Fig. 6 is a detail perspective view of the device or means for adjusting the tension of a spring of a valve for admitting air.-

Referring more especially to thel drawings 1 designates the hood of an autoinobiley?. the radiator, and 3 the internal combustion engine, while 4 denotes the breather, which is patterned after the breather of the Ford automobile. The engine is provided with the usual exhaust manifold 5, and the' in take manifold G. which is connected to the usual carburetor?. Onel end of the casing of the carburetor is provided with a cylindrical nipple or extension 8,and by means of acl-amp 9 an upstanding tubularcasing 101s fastened to the 'breather 4. `'Ihis clamp 9"consists of two sections 11 and 12, which are hingedly united as shown at 13. `The section 11 of the clamp is integrally connected to the tubular casing 1G by means of the strap extension or bar 14. The free ends of the vsections r1l and 12 terminate in ears 15, through which a thumb screw 16 extends, for clamping the sections of the claniip about the exterior of the end portion of the breather 4. It is to be noted that the low-er end of the tubular casing 10iits telescopiv'cally into the breather, and the extension strap or bar 14 engages the upper edge of the breather 4, thereby limiting the casing 10 into the breather. 10 has a laterally protruding tubular eX- tension 16, in which a ystraining member 17 consisting of wire fabric is arranged. The

upper end of the easing 10 has a trans-r verse disk wall 18 provided with perforations 19. A tubular guide20 rises concen- 'trioally and upwardly from the Wall 18, in

which a valve stem 21 is guided. The lower end of the stem carries a disk valve 22, to

lmove toward and from the wall 18, for closing and opening the perforations 19. The upper end of the stem 21 is threaded, and mounted thereon are nuts 23 and 24, there being a lock washer 25 between the two nuts. This washer is split as shown at 26, and has one of its ends 27 deflected, so as to bind against the nut 24, -in order to look `The tubular casing I speu bi u l Q.. 1. 1 1. 1 i l 1.. on 1. i S f.\ Px. u J .I 1 l A[L ...L
